Research on improving a problem of the cluster-heads'''' death in a round using a variable round method
使用变长轮方法改善轮内死亡问题的研究

To solve the problem of cluster-heads' heath in the LEACH-based algorithms for WSNs, a variable round mechanism was proposed in this paper. It effectively solves the problem that when the rounds last too long, it appears that cluster-heads die in the rounds and when the round time is too small, the overhead energy wastes and the frequent alternation takes place. The simulation shows that the method of variable round enhances the efficiency in energy-consumed and the usability of WSNs.
